Abstract: Disclosed herein are polymer compositions useful for inhibiting corrosion of metal surfaces in industrial process water recirculating systems. The polymer compositions include interpolymers of about 90 mol % to about 97 mol % of a first monomer, about 0.01 mol % to about 5 mol % of a second monomer that is chemically different from the first monomer, and about 0.01 mol % to about 5 mol % of a third monomer that is chemically different from the first and second monomers; and optionally a fourth monomer that is chemically different from the first, second, and third monomers. About 0.05 ppm to about 200 ppm by weight of the polymer composition is dispersed in an industrial process water source, optionally in the presence of a divalent or higher valency metal ion. The dispersed polymer compositions significantly reduce the corrosion rate of metal surfaces of industrial equipment, even after one or more cycles of concentration.

Abstract: Disclosed herein are polymer compositions useful for scale inhibiting applications. The polymer compositions include a plurality of monomers, which include at least one carboxylic acid and a sulfonated acid. The polymer compositions are used in polymer mixtures in water sources for inhibiting scale formation at relatively low dosages.
